2.1 Functional principle

The HISIC450 overheight detector comprises two photoelectric switches that are installed

at the same height and whose beams run in opposite directions. Two photoelectric

switches are used to reduce false alarms caused by birds, leaves or other objects.

Reliability can be further increased when induction loops are used in addition to the photo-

electric switches.

Some options for the evaluation of the signals of the photoelectric switches are described

in → p. 17, §4.

2.2 Special features

● High light intensity for use in almost any weather condition.

● Resistant to snow, rain and dust.

● Aluminium housing with anticorrosive coating.

3.1 Project planning

3.1.1 Installation planning

Observe the following when planning installation:

● The distance between the two photoelectric switches (d

in → Fig. 2) is normally 1 m.

● Maximum measuring distance (d

in → Fig. 2) see → p. 30, §8.1.

Fig. 2 Distances and arrangement of photoelectric switches

● The installation height (upper edge of housing) is equivalent to the maximum vehicle

detection height.

● The two photoelectric switches have to be installed so that the direction of the light

beams is in the opposite direction to each other. This means that a transmitter and a

receiver must be installed on each side of the road (see → Fig. 2).

● Sunlight must not shine directly or via a reflection into the optics of the receiver.

● For photoelectric switches used outdoors, an overvoltage protector must be installed

because overvoltage caused by thunderstorms can not be discharged within the

devices.

● To increase reliability, it is recommended to use induction loops in addition to the photo-

electric switches.

3.1.2 Object detection limits

Minimum object diameter

The prerequisite for the detection of objects is that they fully cover the receiver optical

system of the photoelectric switches for the duration of the reaction time. This implies that

moving objects must be larger the faster they move. The minimum size of an object thus

depends on the speed of the object, the reaction time of the photoelectric switches and the

size of the receiver optical system and results from the following formula:

Example:

– Width of receiver optical system: 35 mm

– Reaction time of photoelectric switch: 500 μs

– Maximum object speed: 100 km/h (



27.8 m/s)

This results in the following minimum object diameter:

If smaller objects are also to be recognized, the width of the receiver optical system can be

reduced to 20 mm by applying black paint (see → Fig. 3).

Fig. 3 Reduction of receiver optical system

Minimum object speed

To trigger an alarm, both photoelectric switches must detect the object within a predefined

time interval. This requires a certain minimum speed of the object below which no alarm is

triggered. This minimum speed depends on the distance between the two photoelectric

switches (d

in → Fig. 2) and the time interval.

Example:

– Minimum object speed: 5 km/h (



1.39 m/s)

– Distance between photoelectric switches: 1 m

– Time required for the distance between the two photoelectric switches:

1m/1.39m/s = 0.72 s

This means that the time interval used in signal evaluation has to be 0.72 s minimum.

Signal Evaluation

4 Signal Evaluation

Signal Evaluation

Subject to change without notice

The photoelectric switch signals of the HISIC450 can be evaluated via an external PLC (not

included in scope of delivery of HISIC450). This can be performed in many ways. The

description of a simple hardware wiring in → §4.1 and → §4.2 and of two signal evaluation

options by means of PLC in → §4.3 serve as examples.

4.1 Simple AND circuit

This evaluation is advisable only for device variant HISIC450-R.

1 For the first photoelectric switch in driving direction, set a switch-off delay that matches

the minimum object speed (see → p. 13, §3.1.2; recommended are approx. 2 s) (see

→ p. 16, §3.5.3).

2 Set a switch-off delay of 0.5 s minimum for the second photoelectric switch.

3 Connect the outputs of both photoelectric switches in series on the hardware side.

With this evaluation, a reduction of false alarms by direction detection is not possible.

The wiring shown in → Fig. 6 for a light-ON photoelectric switch is a recommended solution

for wire break protection.

Signal Evaluation

4.2 Direction-dependent evaluation

This evaluation can be performed with different PLC methods. As an example, a program is

described in the following which is similar to the contact plan of the “easy” control relay by

Moeller.

In this evaluation, the first signal has to come from the first photoelectric switch, the

second signal from the second photoelectric switch. If a signal from the second photoelec-

tric switch comes first, signals from the first photoelectric switch are suppressed until the

second photoelectric switch is uncovered again and the delay time T2 has expired.

Fig. 7 Direction-dependent evaluation

Row 1: T1 is activated when T2 is not active, i.e. when the first photoelectric switch was

first interrupted.

Row 2: T2 is activated when T1 is not active, i.e. when the second photoelectric switch was

first interrupted.

Row 3: Overheight alarm (Q1) is triggered when I2 is output while T1 is still active, i.e. when

the second photoelectric switch is interrupted before the delay time of the first photoelec-

tric switch has expired.

Rows 4a to 4c: The alarm is acknowledged when the light path of both photoelectric

switches is uncovered again.

The delay time of the photoelectric switches (see → p. 16, §3.5.3) should be set high enough

that the PLC can reliably read in the signals (depending on the PLC used and possibly its

cycle time).
